Radon Detection and Reduction questions, answered by experts

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.
